Methanol Synthesis from CO₂ and H₂O Using a Solid Phosphate Electrolyzer at 240 °C and 28 Bar

It has been demonstrated that it is possible to produce methanol in one step reasonable amounts by electrolysis of CO 2 and H O gasses dissolved under 28 bar at 240 °C contact with an electrolyte consisting solid CsH PO 4 additions polyvinyl butyral (PVB) acting as a binder. The cathode was designed sandwich layer copper catalyst porous platinum electrode. anode consisted ruthenium metal covered RuO . system operated current densities up ca. 100 mA cm −2 voltage less than volts producing Faradaic efficiency 7%. There seems be nothing against recirculating the rest reactant gases improve conversion. question course whether present approach can compete more traditional conversion starting electrochemical produced hydrogen.
